2. In medium and high speed driving
Return port
1. The shaft operation force of solenoid rod is reduced due to the reduction of output current from ECPS control unit.
2. The coil spring pulls the PCV spool toward solenoid valve to open it.
3. The hydraulic pressure from pump flows to pinion reaction area through orifice and applies reaction force to reaction
plunger.
4. At this time, the reaction plunger transmits the reaction force to V-groove in input shaft to provide heavy steerability.

ECPS CONTROL UNIT

1. To provide proper steerability to the driver, ECPS control unit controls the solenoid valve by receiving the acceleration
pedal and vehicle speed data via CAN communication.
2. ECPS control unit controls the working current for solenoid valve with PWM type duty ratio of 333 Hz frequency and
sets the target current to 1A during 1 second after IG "ON".
3. When a trouble occurs in the system, ECPS control unit generates a trouble code with using fail safe function.
